Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100740, here are decompositions:

7 + 100733 = 100740
37 + 100703 = 100740
41 + 100699 = 100740
47 + 100693 = 100740
67 + 100673 = 100740
71 + 100669 = 100740
127 + 100613 = 100740
131 + 100609 = 100740

Showing the first eight; more decompositions exist.
